Piezoelectric Humidity Sensors
Measuring moisture accurately is crucial, and a piezoelectric humidity sensor is an exceptional tool for this purpose. Piezoelectric sensors are renowned for their reliability, versatility, and effectiveness in measuring relative humidity (RH).
How Piezoelectric Humidity Sensors Work
Piezoelectric sensors utilize the piezoelectric effect: when a piezoelectric material is subjected to mechanical stress, an electrical charge is generated. In a piezoelectric humidity sensor, a piezoelectric material is coated with a moisture-absorbing layer. When moisture is absorbed, the layer expands, causing a change in the mechanical stress on the piezoelectric material. This change triggers the generation of an electrical charge proportional to the absorbed moisture. The measured electrical charge is then converted into a humidity reading.
